GLEARER-ROLL FOR, DRAVIING, RGVING, AND SPINNING FRAMES.

To all whom it may concern Be it known that we, MAncELLUs GOULD andNELSON C. CLoUnrrn, citizens of the United States, and both residing atPenacook, in the county of Merrimack and State of New Hampshire, havejointly invented a new and useful Clearer-Roll for Drawing, Roving, andSpinning Frames, of which the following is a specification.

Our joint invention relates to drawing, roving and spinning frames inwhich clearer-boards or other cleaning devices are employed as top-rollclearers of accumulating waste, short-fly and dirt, the clearerboardmost commonly in use being attached to the under side of thehinged-metal-cover of the rolls, and provided with a layer or strips offlannel or other like material, which lies lightly upon the top-rolls,for the purpose of gathering up and holding the waste, short-fly anddirt, usually called the clean away, constantly accumulating on theleather-covered top rolls.

It is well known to those familiar with the practical operation ofdrawing, roving and spinning frames, and especially of roving machines,whet-her slubbers, intermediates, fly-frames or jack frames whereinlongstaple cotton is used, that the percentage of the clearaway adheringto the top-rolls, particularly the front toproll, is very considerable,and that constant care must be exercised, and much time employed, inremoving the clearaway from both the clearer-board and the top-rolls,lest the clearaway be drawn into the roving or yarn and form slugs orbunches, frequently resulting in breakages of the roving or yarn.

Ne are aware that cleaning-rolls have been invented for use in machinesof the character above soecified, but they are of such formation, andconcentrically revoluble, that their surfaces, traveling in revolutionat the same rate as the top-rolls, do not have sufficient frictionalengagement with the latter to remove the clearaway, but rather tend tocollect and press the clearaway into bunches on the top-rolls, to be themore readily dropped or drawn into the roving or yarn.

The object of our joint invention is to provide eccentrically revolubleclearerrolls, which shall lay, gravity held, upon a top-roll,

larly described; illustrated in the drawings,

and covered by the claims.

In the drawings, wherein like letters of reference indicatecorresponding parts in all Ithe views :Figure 1 is a transverse sec--tional view of a sufficient portion of a roving machine-fly-frame toshow the adaptation of our invention. Fig. 2 is a top view of a similarsection of a fiyframe with one of our clearer-rolls in operativeposition. Fig. 3 is a view in perspective of our front clearer-roll andso much of the front toproll of a fly-frame and its connecting parts aswill show the manner of operation of the clearerr0ll. I

A is a portion of a roving machine-fiyframe, a top-rolls usually ofiron, leather covered, Z) bottom rolls, steel, fluted, (Z yarn orroving, e hinged metal cover, upright lugs or stops fdr cover, 9 frontclearer-roll, 2 eccentric shaft of clearer-roll, and 7c flaniel coveringof clearer-roll.

In the practical operation of our joint in vention, the frontclearer-roll lies atop the front top-roll, and the rear clearer-rollatop and between the middle and rear top rolls, both clearer-rollsrotated by the top-rolls, with the eccentric shaft of the clearer-rollsbearing against upright lugs or stops and freely movable, up and down,thereagainst, as the clearer-rolls rotate, the rotary motion of theclearer-rolls being sufficiently retarded by the oscillating,longitudinally rubbing movement imparted by said eccentric shaftsmovably bearing against said lugs or stops, whereby the properfrictional engagement is made to insure the taking up of the clearaway.

Our clearer-rolls are covered with flannel or like surface cloth. In theexact type and formation herein shown and described, our device has beenin successful operation without removal for cleaning, for periods ofmore than a week continuously, as compared with the necessary frequentdaily cleaning of the clearer-board so commonly used. It

is found that with the use of our clearerrolls, the tendency of theclearaway to gather on and clog the bearings of the toprolls, especiallythe front top-roll, common in the use of the clearer-board, is obviated.

While we have preferred to construct these clearer-rolls of wood, theymay be made of any other suitable material, which, held to the top-rollsby gravity, will cause the proper frictional engagement with the latterwithout sufficient friction, however,

to appreciably retard the speed of the machine rolls.

Having fully described our invention, we claim:

1. In a machine of the class specified, the

, combination with the top-rolls of a clearing device, consisting of aroller having an eccentric shaft, said roller bearing upon and given arotary motion by said top-rolls, said eccentric shaft bearing againstupright stops and adapted by the free vertical movement of said shaft toimpart an oscillating motion to said roller while rotating.

2. In a machine of the class specified, the combination with thetop-rolls of a clearing device, gravity held in engagement with thetop-rolls, said clearing device consisting of an eccentric shaft and acylinder rigidly mounted on said shaft, said shaft to movably engageuprights attached to the frame, and thereby impart an oscillating andlongitudinal rubbing movement to said cylinder in its rotation.

3. A clearing device for the rolls of drawing, roving and spinningframes, consisting of a roller adapted to lie upon and be rotated bysaid rolls, said roller being circular in cross section and having aneccentric shaft intended to movably engage vertical stops fixed in theframe, whereby said roller in rotating isgiven an oscillating andirregular movement.
